Thanks for your reply.
I changed the name of the executable, but it is still the icon of game guru ...
I have copied the executable on my other computer, but it is still the icon of game guru ...
In my opinion, it is not possible to modify the icon of the executable with this compiled version of Synergy Editor. However, this is the compiled version found on the DBPro Open Source github !
I will appreciate an official response from Game Creators developers. I am annoyed because in the meantime, I can not distribute my program.
Thanks.
